Doodle Jump (99 cents) has been a hit at the App Store since its arrival in 2009 for its simple and addictive gameplay. A new update to the game adds a new look and other fun features, but doesn't tinker much with an already winning formula.
This fun and addictive platform-jumping game features a cute, hand-scribbled aesthetic and a cleverly integrated leaderboard. Not surprising for such an addictive game, the interface couldn't be more simple: you keep jumping automatically, and you gently tilt the device to move left and right. As you move higher and higher up an infinitely scrolling, wraparound vertical screen, you jump onto an increasingly challenging arrangement of platforms -- including moving blue platforms, crumbling brown platforms, white platforms that disappear after one jump, and platforms with jump-boosting springs and jet packs.
